Specification of Letters Patent.

Patented Feb. 26, 11907.

Application filed October 25, 1906. Serial No. 340.435.

To all whom, it may concern:

Be it known that I, WILLIAM D. SNOW, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain- Improvements in the Manufacture of Linoleum, of which the following is a speci fication.

This invention relates to the manufacture of plain and granulated or granite linoleum.

It is particularly adapted for the manufacture of the product having a granite-like or other variegated character, such as is pro duced by mixing compositions of different colors, and forming a layer or sheet of the same upon a woven backing.

The characteristic features of the improvements are found in the operations of feeding and working a proper distribution of the composition upon a backing fabric as it travels horizontally to the calenders, by which it is rolled and secured to the underlying fabric.

In the accompanying drawings, Figure 1 represents a plan view of apparatus designed for the practice of the invention. Fig. 2 represents a side elevation thereof. Fig. 3 represents a vertical sectional view taken hori zontally through the hopper and a portion of the table on the line 3 3 of Fig. 4. Fig. 4 represents an end elevation of the table and hopper, portions being broken away to show the interior construction. Fig. 5 represents a sectional plan view of the end of the hopper; and Fig. 6 represents a transverse sectional view taken through the table, showing the reciprocating mechanism for distributing the composition upon the backing.

As shown in the drawings, the housing 1 of the calendering-rolls 2 and the legs 3 support the table 4, which has an end terminating in a projection 5, disposed in the bight of the rolls. At the end of the table opposite to the rolls is a hopper 6, provided with a fixed bottom plate 7, containing holes 8, and a slide 9, containing holes 10, adapted to register with the holes 8. A threaded rod 11, fixed to the slide, is movable in an end of the hopper, and an engaging nut 12 is swiveled in the bearing 13, these parts serving to adjust the slide so as to vary the openings through the bottom formed by the plate and slide.

A frame 14, movable on the ways 15 has fingers 16 depending therefrom, forming a rake or agitator for working linoleum composition in the hopper through the apertures in the bottom. To reciprocate the agitator, a bolt 17, fixed thereto, is movable in the end of the hopper and is connected by a link 18 with a lever 19, pivoted upon the fulcrum 20. The lever is rocked by the engagement of its slot 21 with the eccentric .22 on the shaft 23, the latter being revolved in the bearings 24 by the pulley 25. composition fed by this mechanism through the openings in the bottom of the hopper at a rate depending upon the adjustment is deposited upon a backing fabric, which is carried from the roll 26 over the roller 27, be neath the hopper, over the table 4, and between the rolls 2.

To distribute the composition upon the backing in the manner desired prior to calendering, a pair of distributors or blades 23, angularly disposed with relation to each other and the table, are reciprocated back and forth. with their edges in the plane of the linoleum surface desired. These blades are fixed, respectively, to the beams 29 by bolts 30, passing through the slots 31 of the blades, the latter being thereby adjustable to provide for producing layers of various thicknesses. Each blade is raised or lowered by threaded rods 32, fixed thereon and passing through interiorly-threaded beveled gears 33, journaled in bearings 34, these gears being operated by beveled gears 35 and 36 on a shaft 37, journaled in bearings 38. The gear 35 is fixed to the rod 37, while the gear 36 is fixed to a sleeve 39, which is revoluble on the shaft by means of a hand-wheel 40. A sleeve 41, connected to the shaft by a spline 42 and revoluble by a hand-wheel 43, is adapted to be moved in and out of engagement with the sleeve 39 by means of the clutching-jaws 44. When it is desired to lift both ends of a blade together, the sleeves 39 and 41 are engaged in clutching relation, when upon loosening the bolts 30 the blade can be adjusted to the desired position and then fixed. When it is desired to adjust Linoleum either end of a blade independently, the cor- 1 supported above said. tablefiandi means for responding sleeve 41 is drawn out of engagement with the sleeve 39 and the wheel 40 or 43 is revolved, depending upon the adjust- -mcnt desired.

the mechanism described the blades are reciprocated.

From the angularly-disposed horizontallyreciprocating blades the backing and the composition distributed thereon are carried through the calenders, by which the composition is pressed into the backing and consolidated.

Having described my invention, I claim- 1. In an invention of the class described, means for feeding composition upon a backing, angularly-disposed devices for distributing the composition fed upon the backing, and means for consolidating the distributed composition and securing it to the backing.

2. In an invention of the class described, devices angularly disposed with relation to each other, for distributing composition and means for reciprocating said devices.

3. In an invention of the class described, a table, means for supplying composition to a backing carried by said table, a reciprocating device angularly disposed with reference to said table for distributing said composition on said backing, and means for consolidating the composition and securing it to said back- 111 i. In an invention of the class described, a table, a pair of distributers angularly disposed with relation to each other and to said table, and means for operating said distributers.

5. In an invention of the class described, a table, a pair of angularlydisposed blades reciprocating said blades.

6. In an invention of the class described, a table, a hopper having a perforated bottom above and feeding directlyvto a backing on said table, an agitator in said hopper, a distributer disposed above said table, and mechanism connected with said agitator and distributer f or operating them.

7. In an invention of the class described, a table, a hopper having a bottom plate with openings therein feeding directly to a backing on said table, a slide having openings registering with the openings in said plate, an agitator in said hopper, a distributer above said table and means for simultaneously reciprocating said agitator and distributer.

8. In an invention of the class described, a table, a hopper having a perforated bottom above and feeding directly to a backing on said table, a rake adapted to reciprocate in said hopper, mechanism comprising a fulcrumed lever connected with said rake, a revolving shaft, and an eccentric connected with said shaft and lever for: operating said mechanism.

9. In an invention of the class described, a table, a hopper feeding directly to a backing on said table a distributer above said table, bearings in which said distributer reciprocates, a revolving shaft, mechanism connecting said shaft and distributer whereby the revolution of said shaft reciprocates said distributer a hopper having a perforated bottom, an agitator in said hopper, bearings in which said agitator reciprocates, and mechanism connecting said shaft and agitator whereby the revolution of said shaft reciproeates said agitator.

In testimony whereof I have hereunto set my name, this 24th day of October, 1906, in the presence of the subscribing witnesses.

WILLIAM D. SNOW.
